Noise Cancellation
Noise cancellation is the practise of eliminating or reducing the amount of background noise in desired signals to improve sound quality. Video conferencing requires crystal-clear audio. Occasionally, its clarity can be compromised by distortion and background disturbances. There are two distortion levels: high and low. Low distortions differ from high distortions by being more "soft." In contrast, a high amount of distortion is characterized by significant interference, prolonged, intrusive noise, and a total change in the voice stream. Clicks, wheezing, rumbling, whistling, humming, and buzzing are the most prevalent disruptions.
Noise classification
Noise can be continuous or sporadic (pulsating). There are two types of constant noise: tonal and wideband. The fundamental characteristics of tonal noise are buzzing and humming. The primary distinction between tonal noise and wideband noise is that the latter has a frequency tint but no distinct band. Broadband noise is characterized by whistling and roaring sounds. It is vital to employ noise-canceling technology to eliminate unwanted noise.
The primary purpose of noise cancellation during a video conference is to eliminate and/or reduce background noise. Most noise cancellation methods lower the quality of the sound being sent, but thanks to new algorithms, the audio stream can be changed so that only small changes can be heard by the human ear.
